passes through the points (−4, 2) and (12, 6)?
Answers
I'll assume you need to find the equation of the line that passes through those points.
Answer:
[tex]\displaystyle y-2=\frac{1}{4}(x+4)[/tex]
Step-by-step explanation:
Equation of a Line:
The equation of a line passing through points (x1,y1) and (x2,y2) can be found as follows:
[tex]\displaystyle y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
The given points are (-4,2) and (12,6), thus:
[tex]\displaystyle y-2=\frac{6-2}{12+4}(x+4)[/tex]
Operating:
[tex]\displaystyle y-2=\frac{4}{16}(x+4)[/tex]
Simplifying, the equation in point-slope form is:
[tex]\mathbf{\displaystyle y-2=\frac{1}{4}(x+4)}[/tex]

Answer:
A is two; B is nine; C is one
Good Luck!
a) C has to be either one or zero (but I'm assuming the solution you're wanting is when C=1). This is because A+B + Whatever is carried can only be a number 0-19, meaning only a 1 can be carried to the third column.
b) if C is 1, then in the ones place, B+A must = 11
c) if the carried 1 + a + b = 10 + a, then a can be substituted and we find that b = 9; and a =2

A store has clearance items that have been marked down by 45%. They are having a sale, advertising an additional 35% off clearance items. What percent of the original price do you end up paying?
Answers
Answer:
35.75%
Step-by-step explanation:
Given that:
Markdown % = 45%
Additional percentage off = 35%
45% markdown :
100% - 45% = 55% of item price will be paid.
Furthermore,
35% additional discount :
100% - 35% = 65% of item price will be paid
Hence, percentage of original price paid:
(55% * 65%) = 0.3575
= 35.75% of the original price is paid

In the figure above, lines l and m are parallel and lines s and t are parallel if the measure of <1 is 35, what is the measure of 2
Answers
Answer: 145
Step-by-step explanation:
145 degrees
The measure of angle ∠2 in the triangle is 145.
Option D is the correct answer.
We have,
From the figure,
The s and t lines are parallel.
The l and m lines are parallel.
Now,
∠1 and ∠a are corresponding angles.
∠b and ∠a are corresponding angles.
This means,
∠1 = ∠a = ∠b = 35
Now,
∠2 and ∠b add up to a straight angle.
This means,
∠2 + ∠b = 180
∠2 + 35 = 180
∠2 = 180 - 35
∠2 = 145
Thus,
The measure of angle ∠2 is 145.

A store sells rope by the meter. The equation p = .8 L represents the price: p (in dollars) of a piece of nylon rope that is L meters long.
How long is a piece of nylon rope that is $2.80?
Answers
Answer:
3.5 meters
Step-by-step explanation:
Equation: p = 0.8L
Given: p = 2.80
To find the length of a piece of nylon rope that costs $2.80, input the given value of p(2.80) into the equation and solve for L:
p = 0.8L
2.8 = 0.8L
Divide both sides by .8 to isolate L:
[tex]\frac{2.8}{0.8} =\frac{0.8L}{0.8}[/tex]
3.5 = L
The length of a piece of nylon rope that costs $2.80 is 3.5 meters long.

Need help ASAP!! Write an informal proof to show triangles ABC and DEF are similar.
Answers
Answer:
Δ ABC and Δ DEF are similar because their corresponding sides are proportional
Step-by-step explanation:
Two triangles are similar if their corresponding sides are proportional which means the corresponding sides have equal ratios
In the two triangles ABC and DEF
∵ AB = 4 units
∵ DE = 2 units
∴ [tex]\frac{AB}{DE}=\frac{4}{2}=2[/tex]
∵ BC = 6 units
∵ EF = 3 units
∴ [tex]\frac{BC}{EF}=\frac{6}{3}=2[/tex]
∵ CA = 2 units
∵ FD = 1 units
∴ [tex]\frac{CA}{FD}=\frac{2}{1}=2[/tex]
∴ [tex]\frac{AB}{DE}=\frac{BC}{EF}=\frac{CA}{FD}=2[/tex]
∵ All the ratios of the corresponding sides are equal
∴ The corresponding sides of the two triangles are proportional
∴ Δ ABC is similar to Δ DEF
